Colorize Selected Tracks or Events button

The Colorize Selected Tracks or Events button in “Audio Part Editor” doesn’t work for me. Someone could check it?
It is necessary to understand, it is the general bug or only my system?

Hi,

Confirmed and reported to Steinberg.

Hi,

the combination Hotkey Shift + Alt + C works without problems, but the button "Colorize Selected Tracks or Events " in the window “Audio Part Editor” doesn’t work.
